Can anybody tell me why in QRH summary (dual hyd failure)...the landing distance calculated(wet cond) take in account the use of reverse..! although you have no reverse available...(green+ yellow)!
You can try by calculating yourself (like we use to do when there were no summary available, this calculation is now done for us in the summary table)for a certain weight, go to the table LAND dist conf full X the factor(multiply the land dist by for wet runway dual hyd failure)x factor for use of reverse, you will end up with the figure mentioned in the summary table.!
Sure i missed something somewhere ..but dont known where...!
Thanks....
